Statistical Analysis of Rounded Data: Measurement Errors vs Rounding Errors [PDF]

Journal of Mathematical Sciences, 2018
Consider the measurements in which the discretization step is constant and without loss of generality is equal to 1. The measured value \(X\) is rounded to the closest integer \(X^*\) according to the rule \(X^*=[X+0.5]\) where \([x]\) is the integer part of \(x\). Measurements of the quantity \(\mu\) are considered as i.i.d. random samples \(X_1,\dots,

A non-local method for robustness analysis of floating point programs [PDF]

Electronic Proceedings in Theoretical Computer Science, 2012
Robustness is a standard correctness property which intuitively means that if the input to the program changes less than a fixed small amount then the output changes only slightly.
